Orion xs1400 question

Can the 1400 be used to charge two 12v 100ah lithium phosphate batteries from a 24v inverter system? I assume yes…. Can I use the same at the same time to feed all the 12vdc loads within the coach.

I’m under the impression that during charging the charger steps amperage or current would that do anything to the loads?

The loads will draw what they need to draw for themselves, the same as the battery.

For the 2x12v side, ideally the two would be sharing a bus bar and be at the same voltage.
